Vitamin B1 in Whole Blood and Vitamin B6 in Whole Blood/Plasma - UHPLC

Order No.: 52952/UHPLC/RUO, for 1000 tests
Parameters:
Vitamin B1 (TPP, thiamine pyrophosphate), Vitamin B6 (PLP, pyridoxal 5’-phosphate)

UHPLC separation in less than 3 min
Each analyte is safeguarded by a specific internal standard

Vitamin B1 (TPP, thiamine pyrophosphate)

Vitamin B6 (PLP, pyridoxal 5’-phosphate)

The Chromsystems UHPLC kit for the combined analysis of vitamin B1 in whole blood and vitamin B6 in whole blood or plasma research samples combines the features of the proven HPLC method with the distinct advantages of UHPLC technology. The efficient sample preparation with Pre-mixed Tubes involves only one precipitation step and subsequent derivatisation. Analyte separation takes approximately 3 minutes. Both analytes are safeguarded by specifically developed internal standards. Quality controls are also available separately.

Specimen Whole Blood and Whole Blood/Plasma
Sample Preparation
  • Mix 200 μl reserach sample/calibrator/control with 100 μl Internal Standard and 300 μl Precipitation Reagent in an amber vial (light protection) and shake 30 s (vortex).
  • Centrifuge for 5 min at 14000 x g.
  • Pipette 100 μl derivatisation mix into a labelled Pre-mixed Neutralisation Tube. Add 250 μl supernatant obtained above, mix briefly.
  • Incubate for 25 min at 60 °C (waterbath).
  • Cool sample for 10 min at +2 to +8 °C, then centrifuge for 2 min at 14000 x g.
  • Transfer the supernatant into a light protected autosampler vial, inject 2.5–10 μl into the UHPLC system.
Run Time 3 min
Injection Volume 2.5–10 μl
Flow Rate 0.7 ml/min
Column Temperature ambient (~ 25°C)
Wavelengths

Start: EX 320 nm, EM 415 nm
After approx. 1.6 min switch to EX 367 nm, EM 435 nm

Additional Info

For the combined UHPLC analysis of vitamins B1 and B6 in whole blood and plasma, any major UHPLC system with binary pump and programmable fluorescence detector is suitable.
